ANSWER
It is horizontally compressed by a factor of 2 and reflected over the y-axis.
EXPLANATION
The parent function given to us is
The parent function has been transformed to obtain
This transformation is of the form:
If
then,there is a horizontal compression by a factor of k.
Hence
is horizontally compressed by a factor of 2.
Since -2<0, it is a reflection in the y-axis.
The correct choice is the last option.
Answer:
x = 20
Step-by-step explanation:
3x - 10 = x + 30
2x = 40
x = 20
Answer:
Since x=2 is a vertical line, there is no y-intercept and the slope is undefined.
Step-by-step explanation:
Answer:
(a) $2000
(b) $94.9
Step-by-step explanation:
The expected $ value of signing 100 deals with probability of 0.1 each is
E(X) = 100*0.1 + 100*0.1 + 100*0.1 + ... + 100*0.1 = 100(100*0.1) = $1000
Along with the fixed amount of $1000, the total next month salary is $2000
As for the standard deviation we can apply the following formula
Hello:
equation is the line is : y = ax+b a is a slope
y = (-3/4)x+b
<span>passing through the point (−3;−3) : -3 =(-3/4)(-3)+b
y = (-3/4)x-(21/4)
</span>We draw the <span>Graph by two points : A(-3;-3) B(0;-21/4)</span>
